upgrading from 440 to 450

[Harvey]

New to direct soft.  I am upgrading from 440 to a 450.  The problem I am having is with the 450 the temp on a thermocouple card f4-08thm-j card is modulating.  go from 78 degs then to 115 then to 312 back to 78. (using two cards)same problem with both. Not sure how to fix this.  As far as I can see the registers are right.this is the code from the 450.  thank you for your time.

What board are you using?

The DL450 is excellent for using the Ibox!
